When is the prostration for forgetfulness performed before the closing salam, and when is it performed after it?
Machine translationRead the Arabic original
O Shaykh, when is the prostration performed before the closing salam, and when is it performed after the closing salam?
The prostration is performed before the closing salam, except in two cases; this is the preferred practice:
One case: if one says the closing salam while missing a unit of prayer or more, he completes the prayer and performs the prostration for forgetfulness after the closing salam.
The second case: if he builds his prayer on his predominant belief, he completes the prayer, says the closing salam, and then performs the prostration for forgetfulness.
In the remaining cases, it is performed before the closing salam; this is the preferred practice.
